A simple question,linux monitoring tool like Cockpit

This is a screenshot from "cockpit", a nice app of Fedora server,I can see from it disk,network,ram usage for host.

The good thing is start preconfigured for host.
My question is..someone know a app like this which can monitor a entire network of linux hosts?Maybe preconfigured like Cockpit?Maybe open source?Thanks
I know Cacti..some other alternatives?
